DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1A and 1B, which are outward and inner structural diagrams of the car charger 10 a respectively according to one embodiment of the present invention. The car charger 10 a has a shell 11, a charge circuit (not shown), an anode conduction section 13 a, a cathode conduction section 15 a, and an operation section 20 a. In FIG. 1B, the anode conduction section 13 a is placed in a carrying base 201 a of the operation section 15 a. The cathode conduction sections 15 a is set at two sides of the carrying base 201 a. One end of the shell 11 has an aperture for the anode conduction section 13 a to stick out, and the shell 11 also has strip shape holes for the cathode conduction sections 15 a to reach out. Thus, the anode conduction section 13 a and the cathode conduction sections 15 a may connect to the cigarette lighter of a vehicle, so as to capturing electric power from the power source of the vehicle, for providing requisite power to an electronic device.

The charge circuit is the power supply module of the car charger 10 a, for regulating and transforming the electric power captured from the vehicle, and for providing electric power to the electronic device. The shell 11 is the housing of the car charger 10 a, in which the shell 11 has spaces for containing the charge circuit, by doing so, the charge circuit may be protected from outward influences, so the stability of the charge circuit may be improved. The shell 11 may further include a container space for collecting the anode conduction section 13 a and the cathode conduction sections 15 a.

In this embodiment, the anode conduction section 13 a is set at the end of the shell 11 of the car charger 10 a, and is electrically connected to the charge circuit. The shape of the anode conduction section 13 a may be any kind of shapes for fitting in with the cigarette lighter of the vehicle, and the anode conduction section 13 a may be made of conductive materials for capturing electric power. The cathode conduction sections 15 a are set at two sides of the shell 11, for connecting to the conductive sections of the cigarette lighter of the vehicle. The cathode conduction sections 15 a may be made of conductive materials, and may be elastic strips or slices.

As shown in FIG. 1B, the operation section 20 a of this embodiment may include a carrying base 201 a and a slide positioning component 203 placing at the spaces between a first shell 111 and a second shell 112. The carrying base 201 a is for carrying the anode conduction section 13 a, so the anode conduction section 13 a may not move irregularly. The carrying base further includes a support section 205 a which is connected to the cathode conduction sections 15 a for fixing the positions of the cathode conduction sections 15 a. The slide positioning component 203 is connected to the carrying base 201 a. In this embodiment, the sides of the slide positioning component 203 may have side bars 2031 corresponding to a plurality of slide positioning slots 119 of the shell 11.

Part of the slide positioning component 203 reaches out of the shell 11, thus the users may push the slide positioning component 203 for making the side bars 2031 move between the slide positioning slots 119 of the shell 11, in order to move the carrying base 201 a. When the carrying base 201 a moving, the anode conduction section 13 a moves along with the carrying base 201 a, and the cathode conduction sections 15 a is stretched or bended by the support sections 205 a. Thus, the anode conduction section 13 a and the cathode conduction sections 15 a may be selectively collected within the container space of the shell 11.

Additionally, the shell 11 may include at least one rib 117, for fixing the position of the carrying base 201 a of the operation section 20 a, so that the carrying base 201 a may not move unexpectedly. The car charger 10 a may further include a connection interface 19 which may be a universal serial bus (USB) connection interface, for connecting to the electronic device.

Please refer to FIG. 2A and 2B, which are outward and inner structural diagrams of the car charger when the conduction sections are collected according to the embodiment of the present invention. As shown in the figures, because the carrying base 201 a may be moved by users, so the anode conduction section 13 a may be selectively collected within the shell 11, and the cathode conduction sections 15 a may be stretched and collected within the shell 11.

Additionally, as shown in FIG. 3 which is a structural diagram of the operation section 20 a of the embodiment, the carrying base 201 may have at least one slide slice 207 corresponding to at least one slide track 115 of the second shell 112. According to the slide slices 207 and the slide tracks 115, the carrying base 201 a may be moved in a predetermined direction. Furthermore, one end of the cathode conduction section 15 a may be fixed at the shell 11, or be fixed at a bump setting at the shell 11, for avoiding poor electrical contact induced by irregular positions of the cathode conduction sections 15 a.

Please refer to FIG. 4A and 4B, which are outward and inner structural diagrams respectively of the car charger 10 b according to another embodiment of the present invention. The car charger 10 b includes a third shell 113, a fourth shell 114, an anode conduction section 13 b, cathode conduction sections 15 b, a charge circuit (not shown), and an operation section 20 b.

In FIG. 4B, the operation section 20 b has a carrying base 201 b, a rotation hinge 206, and a rotation positioning component 209. Wherein the carrying base 201 b is for carrying and fixing the position of the anode conduction section 13 b. The carrying base 201 b may further have support sections 205 b connected to the cathode conduction sections 15 b. The rotation positioning component 209 is connected with the rotation hinge 206 of the fourth shell 114. When the fourth shell 114 is rotated along an axial direction by users, the rotation positioning component 209 may also be rotated and pushes a pushing slice 211 of the carrying base 201 b. Thus, the carrying base 201 b may slide and making the anode conduction section 13 b to move and the cathode conduction sections 15 b to stretch or bend.

In FIG. 4A and 4B, the anode conduction section 13 b and the cathode conduction sections 15 b are reaching outside the shell 11. When the user rotates the fourth shell 114 along the axial direction, as shown in FIG. 5A and 5B, elastic components 213 may push the carrying base 201 b by contacting the blocking slices of the third shell 113 for collecting the anode conduction section 13 b and the cathode conduction sections 15 b within the car charger 10 b.

Alternatively, as shown in FIG. 4C, the operation section 20 b be implemented as a carrying base 201 b, a connecting component 208, and at least one cross point 210. The carrying base 201 b is connected with the fourth shell 114, which is the rear part of the shell 11, by the connection component 208. The cross point 210 is set at the surface of the connection component 208 corresponding to a cross slice 212 of the third shell 113. When user uses the car charger 10 b, the third shell 113 may be shifted toward the fourth shell 114, so that the cross point 210 is blocked by the cross slice 212 for keeping the anode conduction section 13 b and the cathode conduction section 15 b reaching outside the third shell 113.

On the other hand, when the user wants to collect the anode conduction section 13 b into the car charger 10 b, the third shell 113 may be shifted for covering the anode conduction section 13 b and the cathode conduction section 15 b. As shown in FIG. 5C, in this situation, the cross point 210 is not blocked by the cross slice 212, so the third shell 113 is pushes slightly outward from the fourth shell 114 by the elastic component 213 for covering and collecting the anode conduction section 13 b and cathode conduction section 15 b into the car charger 10 b. Additionally, the third shell may further includes an extended shell 214 for covering the connection component 208 which may be revealed when the third shell 113 is shifted slightly outward from the fourth shell 114.

In another embodiment, the rotation hinge 206 may also be designed for being rotated along a radial direction. Thus, because of the radial-directed rotation hinge 206, the anode conduction section 13 b and cathode conduction section 15 b may be selectively collected by folding the third shell 113 with the fourth shell 114.

Please refer to FIGS. 6 and 7, which are schematic diagrams of the car charger 10 c according to still another embodiment of the present invention. The car charger 10 c has an anode conduction section 13 c, cathode conduction sections 15 c, charge circuit (not shown), and an operation section 20 c. In this embodiment, the operation section 20 c includes a rotation component 215 and a slide piece 217. The rotation component 215 is connected to the fourth shell 114 of the car charger 10 c, and the surface of the rotation component 215 has at least one spiral thread. The slide piece 217 is connected to the cathode conduction sections 15 c, and has at least one dimpled grain corresponding to the spiral thread. When the user rotates the fourth shell 114 of the car charger 10 c, the rotation component 215 is rotated along with the fourth shell 114. With the combination of the spiral threads and the dimpled grains, the slide piece 217 is moved forward and backward, so as to stretch or bend the cathode conduction sections 15 c for collecting the sections 15 c within the car charger 10 c.

Additionally, for improving the convenience of carrying the car charger, the shape of the car charger may be designed as a thin four-corner pillar. The thin appearance of the car charger may reduce the volume and weight of the car charger. Certainly, the shape of the car charger may be designed in any shape by any manner.

As described above, by setting up operation section with the car charger, the anode and cathode conduction sections may be collected within the car charger. Therefore, the practical value and the convenience of carrying the car charger may be improved according to the present invention.
